Generating string field theory solutions with matter operators from algebra
Hiroyuki Hata, Daichi Takeda, Jojiro Yoshinaka
The algebra is a subalgebra that has been used to construct classical solutions in Witten's open string field theory, such as the tachyon vacuum solution. The main purpose of…
Interior Product, Lie Derivative and Wilson Line in the Subsector of Open String Field Theory
Hiroyuki Hata, Daichi Takeda
The open string field theory of Witten (SFT) has a close formal similarity with Chern-Simons theory in three dimensions. This similarity is due to the fact that the former theory h…
Bernoulli Numbers and Multi-brane Solutions in Cubic String Field Theory
Hiroyuki Hata
In a previous paper [arXiv:1901.01681], we presented an analytic construction of multi-brane solutions in cubic open string field theory (CSFT) for any integer brane number. Our $(…
Analytic Construction of Multi-brane Solutions in Cubic String Field Theory for Any Brane Number
Hiroyuki Hata
We present an analytic construction of multi-brane solutions with any integer brane number in cubic open string field theory (CSFT) on the basis of the algebra. Our solution…
BV Analysis of Tachyon Fluctuation around Multi-brane Solutions in Cubic String Field Theory
Hiroyuki Hata
We study whether the tachyon mode exists as a physical fluctuation on the 2-brane solution and on the tachyon vacuum solution in cubic open string field theory. Our analysis is bas…
Inversion Symmetry of Gravitational Coupling in Cubic String Field Theory
Hiroyuki Hata, Toshiko Kojita
It was found that the canonical energy of multi-brane solutions in CSFT constructed by the KBc algebra has a symmetry under the exchange of K=0 and K=\infty (inversion symmetry). O…
